Fish Handling & Restraint  Identify w/ numbered jaw tags, button tags inserted through fins or an operculum, freeze branding, fin clipping and pigmentation patterns.  Wild-caught - no mud on gills & not injured, no damage to protective mucus coat  Not kept out of water more than a few seconds, without equipment to keep their body & gills moist  Temperature, pH & O 2 level of transport water should not vary from water taken from.  Plastic bags & Styrofoam boxes for transport  Shipment requires water oxygenation system.  Can use anesthetics for long-distance shipment

Ferret Handling & Restraint  After adjusting, handle without difficulty & restraint gloves. Females with babies are aggressive.  Hold adult by grasping it behind front extremities with 1 hand & holding hind legs with other hand.  1 hand across shoulders, thumb & forefinger around neck, other fingers around chest behind forelimb  Held by loose skin in back of neck, animal will relax & simple procedures can be performed.  Foul-smelling substance may be emitted (not sprayed) from scent glands located on either side of anus.

Chinchillas  Belongs to same family as guinea pig  Normal wild color is a smoky blue-gray.  Nutrition studies, studies of middle & inner ear  Caution in handling because of risk of fur-slip.  release fur when attacked or frightened  To pick up, tail is grasped and animal swung onto opposite forearm & held against handler’s body where it will usually sit quietly.

Chinchilla Husbandry  Adults, especially females, aggressive & may have to be caged individually.  commonly maintained in pairs  Wide variety of caging with solid or mesh bottoms  mesh is more suitable, since cleaning is easier  Takes dust bath; fur appears matted & rough without frequent access.  A pan or box with a mixture of Fuller’s earth & white sand placed in pen daily.  If dust bath is left in pen, there is a perpetual cloud of dust in room, as they are active in their dusting and grooming habits.

Chinchilla Diet  Commercial chinchilla pellets  long, thin capsules, grasped readily in one forepaw  Grasp food with paws & may throw pellets  Some breeders feed only commercially prepared food, giving no hay or greens.  Other breeders believe that hay is necessary for nutritional or behavioral reasons.  Some believe that best results are obtained by using vitamin or protein supplements.

25
Woodchuck Husbandry  Adults may be housed in standard metal cages designed for cats, dogs or rabbits.  Doors must latch securely. Food & water bowls & cage floors clamped so cannot be pushed or slid out.  Squeeze through any hole large enough for head.  Raised flooring is preferable to contact bedding, as animals kick bedding from cages.  Adult s can be housed in groups in large cages.  Housing in groups less than 2 may result in food monopolization by dominant individuals.  Adult males must be housed individually.  Place each male with 1 female mate.

27
Opossums  The only North American marsupial  Marsupials s have pouch where young carried.  Some 90 living species in 11 families; found mainly in Australia, in South & Central America.  Wild caught North American opossums used.  Not bred in captivity to develop any special strain.  Experimental studies in developmental biology  Young born premature (12–13 days gestation).  Used to study fetal development outside uterus.  Brazilian gray short-tailed is hamster-sized, no pouch, carries young on abdomen; young readily accessible for study.

Armadillos  Nine-banded included in anteaters & sloth group  Susceptible to leprosy & is first unaltered model capable of developing form of disease that is difficult to treat.  Important characteristics for research are:  production of monozygous quadruplet young  simple uterus similar to human  implantation delay of the blastocysts  low body temperature of 80 to 97.5°F  ability to build up an oxygen debt  band patterns on the shell which readily mutate  primitive immune response

32
Armadillo Diet  In the wild, eat insects.  Traditional captive diet = milk, eggs, & chopped raw meat & can maintain them for long periods.  Diets based on canned dog or cat food with vitamin K and some fruits added.  To adapt newly captured to laboratory diet, give no food for 2 days & offer laboratory diet as a soupy mixture in place of drinking water.  will drink this to obtain the moisture
